In news that may be seen as somewhat surprising by many, the upcoming Walt Disney biopic Saving Mr. Banks has been rated PG-13 for “thematic elements including some unsettling images,” ComingSoon.net is reporting. The movie–which is apparently finished now, given that it has an MPAA rating–chroncles Disney’s efforts to coax  P.L. Travers into letting him adapt her Mary Poppins stories into a feature film. Starring Emma Thompson as Travers and Tom Hanks as Walt himself, the film comes to theaters everywhere this Christmas.
